This particular call to exportData is probably equivalent in effect to the R call:

write.table(MU.Cost,

	file = paste("C:/RAUDSL/S",
			    as.character(MU.Cost$Run.Id[1]),
				".",as.character(MU.Cost$MU.Id[1]),
				".MU.PRICE.OUTPUT.txt", sep=""),
	append = FALSE)

as Barry sort of guesses, but in general exportData handles a wide variety of data export facilities, including writing to odbc connexions, so other uses of exportData would need the RODBC library in R and functions like sqlSave or sqlUpdate.

write.table is also an S-PLUS function as well, but exportData is generally a whole lot faster.

  Looks like perfectly good R to me.

  Except there's no exportData function. I assume this is an Splus function that R doesn't have, in which case telling us what it does might help. What does the Splus manual have to say about it?

I'm guessing R's write.table might be of use.

  Assuming its exportData that has you stuck - the other bits should allwork in R no problem, all it does is construct a path from parts of the MU.Cost object.
